I'm not sure how I feel about action against the cartels. I will leave that to people who are much more well-versed on this stuff than me.
This bolded section seems laughable. Absolutely laughable.
Basically by being a a huge part of the Mexican economy, they are highly visible. I seems very unlikely this could turn into much of a guerilla conflict, which has been the only type of conflict that we have struggled with in the past 60 years.
If they decide to hide in the mountains or jungles, then there could be problems... but that would make it difficult for them to make money off their illegal activities.
At least that is how it seems to me...
